Crack 7zip Password Protected Archive [Hack]

7zip is the most recommended way of compressing the files into an archive. It is an opensource tool which allows quick compression and extraction of 7zip, Gzip, Zip, Rar, and other archives. Most users tend to lock the 7zip file with a password but hackers can still extract the archive by bypassing the password. Let me explain how.

7z Cracker is an opensource cracking tool which can extract any password protected 7zip file. It is developed for the purpose of helping users recover their files if they have forgotten the password.

The process is pretty straight forward, once you extract the 7z Cracker, grab the 7zip command line tool called 7za.exe(link given at the bottom of this post) and put it inside the same directory where 7zCracker is residing. Also move the password protected 7zip file (that you want to crack/extract) into the same directory. Now start 7zCracker.exe and enter the archive name along with the extension as shown in the screenshot below.

Once you hit Enter, the 7zip archive will be extracted and you will find the content inside the est folder.

Editor’s Important Note: While adding files to 7zip archive, just below the passwords field there is an option to encrypt the file name. While testing I observed that once this option is checked, 7zCracker will not be able to extract your files. So next time you password protect your 7zip archive, make sure that you have selected an option to encrypted the files as well.

Worked for me 5/24/2012! You never see the pw, but it extracts all the files! Fantastic. Thank you.

I've created archives with different passwords,it always writes that my password is '1' and creates empty files.

Nakodari

It writes that password is 1 but the files are extracted successfully inside the 'est' folder.

No its not… check the files! They’re empty. This tool is crap. It is exactly as good as claiming the regular 7za app can extract passworded files just by entering a random password. It extracts it, but they corrupted.

Delete the est folder and run it again. i have a core i5 and its running at 9 passwords per second all numbers atm. wud take a year to crack a basic pass

mate, perhaps your actual files are encrypted as mentioned, or are you extracting a self-protected 7zip ? Why i ask, is I am distributing 7zip protected works, and once we are paid, we will send the client the password. I’m just trying to find out if 7zip are secure or not, and if not what’s out there that we can use. I know zips are rars are no longer secure and havnt been for some time.

Best regards, i hope you have more success, for your sake, and not mine

Can this work with a series of 7zip archives that belong to one set?

it seems it only works fine with protected 7z files created with the option “Encrypt file names” checked. otherwise, it returns an empty file with ‘1’ as a password, as mentionned by zeragual.

niva

oops sorry… the editor noticed already the “Encrypt file names” trick. so you can suppress all my comments…

Fortunately, this tool does not work on the latest version of 7z – April 2010

This tool is just a simple C prog that tries the password 0 to 99999999 and doesn’t show any progress nor uses letters or special chars. So it’s mainly a simple program from someone who tries to learn a programming language, nothing more. It will fail on nearly all standard passwords, has no dictionary and prints no errors on wrong usage.

I agree

Mike

So it’s just a really shitty brute force password cracker?

Tom

Testet with some file’s

Is this a fakeprogramm ???

Jones Peres

Useless

xD

after 2 h im still waiting to find the code .. this program find letters and numbers or only numbers?

mac

useless! wasteoftime…

doom

it can only crack number passwords!!!!!

DMG

This worked for me. Didn’t print the password it found (printed’1′) but was able to decrypt a few files and put them in an ‘est’ folder it created.

Thanks

Liesontruth

Not worth it..

Roy_somraj

I have facing the same problem like others. it’s show me ” password is 1″

naji7000

put and run all of the necessary files on your hard drive ROOT directory

arinjoy

i have a rar and zip passwpord protected file which i need to convert to 7z first then crack………..how to convert without giving the password?????

karanp1997

it says that archive not found even though i copy the archive name into the cracker

Jacob Chacko

Thanks, it worked.

KP

will this crack password for extracting .exe files for packaging purposes?

yoo

28 hours and still searching… omg…

Fool

Not working

ty

It created all the directories and files within the .7z, but the files were all o bytes and nothing cameup when i tried to open them.

skidmark

No chance i’m guessing the password, does this work or not?

anonymous

Thank you so much! now all the wifi passwords are mine! (i had to d a survey to get pass to use hack)

Music

THIS IS CRAP! IT SAYS TO EXTRACT THE FILE U WANT TO CRACK BUT GUESS WHAT?? I NEED THE PASSWORD TO EXTRACT THE FILE!! BULLSHIT

Amy Tyler

It’s a worthless fake program. Don’t waste your time downloading this because all you will end up with in the “est” folder is what looks like your unzipped files but they will all be 0 bytes. A dog turd is more useful than this thing!

joe

How did I exit the 7zcracker ?……won’t close

joe

How do I*

ohohoh

Ctrl-C

Virgil bom

what to do if the file i wanna to extract is have .part1.rar and .part2.rar…?

its say “Error : can not open file as archive” while it processing archive…

So cracker can extract ANY 7zip files… oh wait… except if you checkmarked the “encrypt box” when you added the files.

Huh?

So cracker can only encrypt files that I haven’t encrypted? That doesn’t make any sense at all.
